CP and MP API Overrides from Config.json (#1992)

* Force useMongoProxyEndpoint to always return true if valid endpoint provided.  Enables new Mongo proxy in all environments.

* Checking MP endpoint in config context.

* Enabling cassandra proxy in all environments.  Requires later cleanup.

* Simplifying and removing endpoint validation since run when config context is generated.

* Enabling one MP API at a time globally.

* Revent to existing CP selection logic.

* Creating list of globally enable CP apis.

* Add list of mongo and cassandra APIs to config and only enable if environment outside existing list of environments.

* Remove environment checks.  If API globally enabled, return true.

* Adding config initialization for mongo unit tests.

* Default to empty enable list to minimize possible impact.  Config.json overrides can be used for testing.
